In a commencement address entitled "The Sinews of Peace" delivered at Westminster College in Fulton, Missouri on March 5, 1946, former British prime minister Winston Churchill painted a picture of the post-World War II world and the emerging struggle between democracy and communism. Although Churchill was out of office, he spoke with all the prestige of "the greatest living Englishman," the charismatic British leader who in 1940 had caught the world's imagination when he proclaimed his country's determination to stand alone against Adolf Hitler's German forces, which had already conquered Western Europe. President Harry S. Truman escorted Churchill when he gave this speech, which he had seen in advance, and which – although Churchill was supposedly speaking as a private citizen – had also been quietly cleared with the British government. Describing the birth of the cold war, Churchill proclaimed that an "iron curtain" had descended across Europe, behind which the Soviet Union exercised unlimited control with no regard for basic human rights. He called upon the United States to join with Great Britain in preventing the further extension of Soviet power. Churchill's phrase caught the popular imagination, and the speech was widely publicized throughout the Western world. The iron curtain metaphor remained in prominent use throughout the Cold War.

When American military men approach some serious situation they are wont to write at the head of their directive the words "over-all strategic concept." There is wisdom in this, as it leads to clarity of thought. What then is the over-all strategic concept which we should inscribe today? It is nothing less than the safety and welfare, the freedom and progress, of all the homes and families of all the men and women in all the lands. And here I speak particularly of the myriad cottage or apartment homes where the wage-earner strives amid the accidents and difficulties of life to guard his wife and children from privation and bring the family up in the fear of the Lord, or upon ethical conceptions which often play their potent part.

To give security to these countless homes, they must be shielded form two gaunt marauders, war and tyranny. [....]

A world organization has already been erected for the prime purpose of preventing war. UNO, the successor of the League of Nations, with the decisive addition of the United States and all that that means, is already at work. We must make sure that its work is fruitful, that it is a reality and not a sham, that it is a force for action, and not merely a frothing of words, that it is a true temple of peace in which the shields of many nations can some day be hung up, and not merely a cockpit in a Tower of Babel....

It would nevertheless, ladies and gentlemen, be wrong and imprudent to entrust the secret knowledge or experience of the atomic bomb, which the United States, Great Britain, and Canada now share, to the world organisation, while still in its infancy. It would be criminal madness to cast it adrift in this still agitated and un-united world. No one in any country has slept less well in their beds because this knowledge and the method and the raw materials to apply it, are at present largely retained in American hands. I do not believe we should all have slept so soundly had the positions been reversed and if some Communist or neo-Fascist State monopolised for the time being these dread agencies. The fear of them alone might easily have been used to enforce totalitarian systems upon the free democratic world, with consequences appalling to human imagination. God has willed that this shall not be and we have at least a breathing space to set our world house in order before this peril has to be encountered: and even then, if no effort is spared, we should still possess so formidable a superiority as to impose effective deterrents upon its employment, or threat of employment, by others. Ultimately, when the essential brotherhood of man is truly embodied and expressed in a world organisation with all the necessary practical safeguards to make it effective, these powers would naturally be confided to that world organisation.

Now I come to the second danger of these two marauders which threatens the cottage, the home, and the ordinary people—namely, tyranny. We cannot be blind to the fact that the liberties enjoyed by individual citizens throughout the British Empire are not valid in a considerable number of countries, some of which are very powerful. In these States control is enforced upon the common people by various kinds of all-embracing police governments. [....] It is not our duty at this time when difficulties are so numerous to interfere forcibly in the internal affairs of countries which we have not conquered in war. But we must never cease to proclaim in fearless tones the great principles of freedom and the rights of man which are the joint inheritance of the English-speaking world and which through Magna Carta, the Bill of Rights, the Habeas Corpus, trial by jury, and the English common law find their most famous expression in the American Declaration of Independence.

All this means that the people of any country have the right, and should have the power by constitutional action, by free unfettered elections, with secret ballot, to choose or change the character or form of government under which they dwell; that freedom of speech and thought should reign; that courts of justice, independent of the executive, unbiased by any party, should administer laws which have received the broad assent of large majorities or are consecrated by time and custom. Here are the title deeds of freedom which should lie in every cottage home. Here is the message of the British and American peoples to mankind. Let us preach what we practise — let us practise what we preach.

I have now stated the two great dangers which menace the homes of the people: War and Tyranny. I have not yet spoken of poverty and privation which are in many cases the prevailing anxiety. But if the dangers of war and tyranny are removed, there is no doubt that science and cooperation can bring in the next few years to the world, certainly in the next few decades newly taught in the sharpening school of war, an expansion of material well-being beyond anything that has yet occurred in human experience. Now, at this sad and breathless moment, we are plunged in the hunger and distress which are the aftermath of our stupendous struggle; but this will pass and may pass quickly, and there is no reason except human folly or sub-human crime which should deny to all the nations the inauguration and enjoyment of an age of plenty. I have often used words which I learn fifty years ago from a great Irish-American orator, a friend of mine, Mr. Bourke Cockran, "There is enough for all. The earth is a generous mother; she will provide in plentiful abundance food for all her children if they will but cultivate her soil in justice and peace." So far I feel that we are in full agreement.

Now, while still pursing the method of realizing our overall strategic concept, I come to the crux of what I have travelled here to say. Neither the sure prevention of war, nor the continuous rise of world organisation will be gained without what I have called the fraternal association of the English-speaking peoples. This means a special relationship between the British Commonwealth and Empire and the United States. This is no time for generalities, and I will venture to be precise. Fraternal association requires not only the growing friendship and mutual understanding between our two vast but kindred systems of society, but the continuance of the intimate relations between our military advisers, leading to common study of potential dangers, the similarity of weapons and manuals of instructions, and to the interchange of officers and cadets at technical colleges. It should carry with it the continuance of the present facilities for mutual security by the joint use of all Naval and Air Force bases in the possession of either country all over the world. This would perhaps double the mobility of the American Navy and Air Force. It would greatly expand that of the British Empire forces and it might well lead, if and as the world calms down, to important financial savings. Already we use together a large number of islands; more may well be entrusted to our joint care in the near future.

The United States has already a Permanent Defense Agreement with the Dominion of Canada, which is so devotedly attached to the British Commonwealth and Empire. This Agreement is more effective than many of those which have often been made under formal alliances. This principle should be extended to all the British Commonwealths with full reciprocity. Thus, whatever happens, and thus only, shall we be secure ourselves and able to works together for the high and simple causes that are dear to us and bode no ill to any. Eventually there may come—I feel eventually there will come—the principle of common citizenship, but that we may be content to leave to destiny, whose outstretched arm many of us can already clearly see.

The dark ages may return, the Stone Age may return on the gleaming wings of science, and what might now shower immeasurable material blessings upon mankind, may even bring about its total destruction. Beware, I say; time may be short. Do not let us take the course of allowing events to drift along until it is too late. If there is to be a fraternal association of the kind of I have described, with all the strength and security which both our countries can derive from it, let us make sure that that great fact is known to the world, and that it plays its part in steadying and stabilizing the foundations of peace. There is the path of wisdom. Prevention is better than cure.

From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the Continent. Behind that line lie all the capitals of the ancient states of Central and Eastern Europe. Warsaw, Berlin, Prague, Vienna, Budapest, Belgrade, Bucharest and Sofia, all these famous cities and the populations around them lie in what I must call the Soviet sphere, and all are subject in one form or another, not only to Soviet influence but to a very high and, in some cases, increasing measure of control from Moscow. Athens alone—Greece with its immortal glories—is free to decide its future at an election under British, American and French observation. The Russian-dominated Polish Government has been encouraged to make enormous and wrongful inroads upon Germany, and mass expulsions of millions of Germans on a scale grievous and undreamed-of are now taking place. The Communist parties, which were very small in all these Eastern States of Europe, have been raised to pre-eminence and power far beyond their numbers and are seeking everywhere to obtain totalitarian control. Police governments are prevailing in nearly every case, and so far, except in Czechoslovakia, there is no true democracy.

[....]

In front of the iron curtain which lies across Europe are other causes for anxiety. In Italy the Communist Party is seriously hampered by having to support the Communist-trained Marshal Tito's claims to former Italian territory at the head of the Adriatic. Nevertheless the future of Italy hangs in the balance. Again one cannot imagine a regenerated Europe without a strong France. All my public life I have worked for a strong France and I never lost faith in her destiny, even in the darkest hours. I will not lose faith now. However, in a great number of countries, far from the Russian frontiers and throughout the world, Communist fifth columns are established and work in complete unity and absolute obedience to the directions they receive from the Communist centre. Except in the British Commonwealth and in the United States where Communism is in its infancy, the Communist parties or fifth columns constitute a growing challenge and peril to Christian civilisation. These are somber facts for anyone to have to recite on the morrow of a victory gained by so much splendid comradeship in arms and in the cause of freedom and democracy; but we should be most unwise not to face them squarely while time remains.

[....]

On the other hand I repulse the idea that a new war is inevitable; still more that it is imminent. It is because I am sure that our fortunes are still in our own hands and that we hold the power to save the future, that I feel the duty to speak out now that I have the occasion and the opportunity to do so. I do not believe that Soviet Russia desires war. What they desire is the fruits of war and the indefinite expansion of their power and doctrines. But what we have to consider here today while time remains, is the permanent prevention of war and the establishment of conditions of freedom and democracy as rapidly as possible in all countries. Our difficulties and dangers will not be removed by closing our eyes to them. They will not be removed by mere waiting to see what happens; nor will they be removed by a policy of appeasement. What is needed is a settlement, and the longer this is delayed, the more difficult it will be and the greater our dangers will become.

From what I have seen of our Russian friends and Allies during the war, I am convinced that there is nothing they admire so much as strength, and there is nothing for which they have less respect than for weakness, especially military weakness. For that reason the old doctrine of a balance of power is unsound. We cannot afford, if we can help it, to work on narrow margins, offering temptations to a trial of strength. If the Western Democracies stand together in strict adherence to the principles of the United Nations Charter, their influence for furthering those principles will be immense and no one is likely to molest them. If however they become divided or falter in their duty and if these all-important years are allowed to slip away then indeed catastrophe may overwhelm us all.
